OILING MECHANISM FOR IN TERNAL-COMBUSTION ENGINES.

Specification of Letters Patent.

Patented J unc 3, 1919.

Application filed January 25. 1919. Serial No. 273,144.

T 0 all whom it may concern Be it known that I, EDWARD J. GULICK, a citizen of the United States, and a resident of the city of Elkhart, county of Elkhart, Indiana, have invented certain new and useful Improvements in ()ilin,g Mechanism for Internal-Combustion Engines, of which the following is a specification.

My invention relates to oiling mechanism for internal combustion engines and more especially to means and devices for separatin deleterious substances from the engine hi ricating oil used in a circulatory system.

As is well known all explosion engines used in motor cars are lubricated from a reservoir or pan of oil usually carried in the engine base or crank case, the lubricant being pumped or splashed upon the hearings to be lubricated, in this system of engine lubrication several quarts of lubricating oil are introduced into the oil reservoir in the engine base and left there until value as a lubricant is materially impaired through continuous use in the circulatory system; which impairment usually occurs after the car has been driven from two to five hundred miles. The entire volume of oil, together with accreted deleterious matter, remaining in the engine base is then drained there from and a fresh charge introduced after thoroughly cleaning the interior of the engine base and oil reservoir,

The impairment of the lubricating, quality of a volume of oil used in the circulatory system of a gas engine is caused by the accumulation of deleterious substances such as carbon, water, dirt and gasolene which gradually accumulate and mix with the lubricating oil and travel therewith through the circulatory system, there being no eflicient method or means now used to separate the oil and deleterious substances and maintain such separation. To effect such a separation ofthe lubricating oil from the deleterious substances mentioned, and maintain it, would mean that each individual charge of lubricating oil used in the oiling system' would not only last much longer but also the lubricating efi'iciency thereof would be greatly enhanced thereby.

An object o my invention is the production of a device and mechanism for effecting and maintaining the separation of dirt, carbon. water, gasolene and other deleterious matter, from the lubricating oil used in directly above the sump 12.

an internal combustion engine. Another ob- ]cct of my invention is the production of a device for exhausting deleterious sub stances extracted from the. lubricating oil without exhausting or drawing off the entire volume of oil from the engine base. Other objects of my invention are mentioned and described herein.

The preferred embodiment of my invention is illustrated in the accompanying drawing in which F igure 1 is a section in elevation taken through an engine base to which my invention is applied; Fig. 2 is an enlarged view in section of the oil reservoir separate from the engine base; Fig. 3 is a section taken on the line 33 of Fig. 2; Fig. l is an enlarged view in section of the drain valve; Fig. 5 is a longitudinal section through a modification of my invention.

Similar numerals of reference indicate like members and parts of members throughout the several views on the drawing.

()n the drawing, the numeral 1 indicates the base or crank case of an multi-cylinder internal combustion engine within which is mounted the usual crank shaft 2 having bearings at 3, 3 and 3. The numeral 4 indicates an oil circulation pump mounted within the engine base and which may be driven by gears 5 and 6 off the crank shaft of the engine. The oil pinup 4: may have a suction intake pipe T and a discharge pipe 8 leading to the various shaft and other bearings for oil cirrulation thereto.

' The engine base 1 may be provided with' a bottom opening 9 which may be covered and sealed by an oil reservoir or pan 10 secured to the engine base in any suitable manner, the pan bottom walls preferably slanting downward from each end to the center of the pan bottom Where a drain valve 11 is placed. In Fig. 2 the pan bottom is provided with a sump 12 upon which the slanting pan bottom walls converge. Numeral 13 indicates a trap box member arranged within the reservoir 10 which is provided with a top wall 14, end walls 15, 15, side walls 16, 16 connected with said end Walls, and a bottom wall 17 which is located intermediate the box extremities and shorter than the top wall of the box, said wall 17 being preferably positioned The walls of the. box member 13 are spaced from the side and end walls of the reservoir 10 to permit cireulat ion the dripping oil to enter the reservoir after thereof. The box 13 is pro vided also with the two bottomopenings 1& and ill in which openings screens 21) and 21 are secured. which screens may be of wire cloth of line mesh, or any other suitable material. A pair of transverse bafl'le plates 2'2 and 23 may be arranged within the box 13 which plates may extend upwardly from the extremities of the bottom wall 17 to the box top all 14. said battles being provided with a plurality of oil circulation apertures '24. Preferably, the screens 20 and 21 are somewhat inclined to correspond with the slant of the bottom walls of the reservoir.

Numerals 25 and 26 indicate a pair of transverse batlie plates extending from the box floor IT to the pan bottom and which may be provided witlrsuitable apertures 27, which ballles may also extendupwardly on each side of the box side walls 16 to a point adjacent the top thereof.

An air vent 28 may be mounted in the top wall H of the box to permit the rise of the oil within the box to the approximate maximum height therein indicated by the dotted line 29. Numeral Sit) indicates an extension of the pump suction pipe 7 which projects through the top wall of the box 13 to the interior thereof and downward into close proximity with the wall 1? and substantially equal distance from the extremities thereof. Numerals 31 indicate bolts for fastening the box 13 within the pan I The effect of the structure described is the formation of settling and oil suction cha1n hers within the reservoir 10, said settling chamber being below the box 13, especially that chamber Elireetly beneath the box bottom 17. and said suction chamber being tne interior of the box 13 from which the strained oil drawn by the pump 4 for circulat ion.

In practice. the pan 10 is tilled with lubrieating oil until the level thereof rises approximately to the dotted line 2 In operation. the lubricating oil is circulated to the engine bearings and drips downward into the pan it! and upon the top of the box 13 whence it flows or is drawn beneath the latter and upward through the screens 20 and 21 to the suction chaniliaa within the 130K 12%. said sereens excluding all dirt, carbon and solid matter from said suction chamber, any water therein flowing by gravity into the sump 1; or into the settling chamber beneath the wall 1T 01' the box 13 where all deleterious substances roilcct and are re taincd until drawn oti'. Periodically, the

deleterious matter collecting in said settling chamber or the sump ll may be drained therefrom by the valve l l without otherwise interfering with the function of the lnbri' eating oil in the pan l0 and fresh oii in like quantity substituted therefor to maintain the desired oil level.

\Yhile the oil flows freely through the screens 20 and 21 from all points thereunder. as indicated by the arrows. there is no circulation therethrough from the sump 12 or the settling chamber beneath the box floor 1? wherein all deleterious substances are. trapped.

The nuna-ral 'd indicates an outlet or drainage opening formed in the bottom the pan it) at the settling chamber or sump thereof, which opening is normally closed by a cylindrical comically faced valve 33 engaging a conical seat surrounding said opening. The. valve 33 is carried by and within a cupped nut 34 which is screw threaded upon the exterior of a hollow cylindrical projection 35 depending from the pan bottom, said valve being mounted in the socket 236 of said nut and substantially centrally thereof. A chamber 37 surrounds the valve 33 and is in communication with the discharge eoenings 38, 38 formed in the head of the wt 34, which openings lead to the atmosphere In operation, when the nut 34 is partially unscrewed. the valve 33 drops from its seat, thereby permittingdrainage of the pan 10 through the settling chamber or sump. partially or Wholly, as desired, and thereby permitting ot' the exhaust of deleterious matter alone without exhausting any quantity of the pure lubricating oil.

In the modification shown inFig. 5 the box 1 is attached to or formed upon the under side of the plate 39 which is bolted between the pan 10 and the lower face of the crank case 1, the plate 39 being provided with suitable oil inlet openings 40. 40 through which the oil may enter after drip ping from the motor above.
